An explaination of the an in-game command. I'd call it a guide. No locking\unlocking of the Shortcut bar is needed for this.

A 1 line command for this would be: /shortcut 1 /tell <name> My LOC is: ;loc

*Replace <name> with your character name.

1. Move the skill that is in Slot 1 to another slot.
2. Copy the command above into the game chat box.
3. Once the command has appeared in Shortcut box 1, move it to another key.
4. Move skill back to slot 1.
